Terminal Blocks – Barrier Blocks

Terminal blocks, also known as barrier blocks, are used to connect multiple pieces of equipment together with a single cable. They are used in a wide range of electrical applications, from industrial to home use. The application field and working principle of 431701-20-0 terminal blocks can be explained in detail below.

Applications

Terminal blocks are primarily used to make electrical connections between two or more electrical circuits, replacing traditional methods such as soldering and crimping. They are commonly used to connect wires for power, signal, data and control. For instance, in the field of automation, terminal blocks are employed to connect field instruments to PLCs, controlling the flow of power and signals throughout the system. In the field of high-voltage electrical distribution, terminal blocks permit current to be safely routed from the source to the destination using conductive connections. They enable the safe distribution of energy and the switching of circuits, preventing the risk of electrocution and system failure due to incorrect connections. Additionally, terminal blocks are used in the electrical and telecommunications industries, as well as in the aerospace and automotive industries. They are often depicted in schematics to indicate connections and wiring systems, as a signal junction point between two circuits.

Working Principle

431701-20-0 terminal blocks employ a barrier block structure. This consists of a number of terminals and an internal barrier, mounted into a plastic insulation housing. The terminals are mounted along one side of the barrier, and are joined to the opposite side via wires, screws or bolts. The terminals can be tinned with solder to ensure a strong mechanical and electrical bond. The terminals can also be tightened with fastening bolts or screws, which ensure a reliable and low resistance connection. The terminal block system also includes a range of accessories such as connection bridges, locking elements and space connection bridges to secure and arrange the incoming cable connections. When a terminal block is fully wired, the flowing current has an uninterrupted path from the source to the destination. This provides a secure connection, reducing the risk of short-circuits and incorrect connections.In conclusion, 431701-20-0 terminal blocks have a wide range of applications and employ a barrier block structure which can be tinned with solder or tightened with bolts and screws to ensure a reliable and low resistance connection. With these terminal blocks, there is an uninterrupted path for current flow, and a secure connection to reduce the risk of short-circuits and incorrect connections.
